10.7 Gate Polarity
Gate polarity is only available in gated burst mode. The generator will output burst when
the gated signal from the [FSK/Trig/Sync/Extmod] connector on the rear panel is "High
Level" or "Low Level".
When Burst is enabled, press Type softkey to select "Gate" and press Polarity softkey
to select "Positive" or "Negative". The default is "Positive".
10.8 Trigger Output Edge
In burst mode, when the trigger source is "Internal" or "Manual", the generator would
output a TTL-compatible signal with specified edge from the [FSK/Trig/Sync/Extmod]
connector on the rear panel.
⚫ Internal trigger: The generator outputs a square waveform with variable duty cycle
(related to the carrier period and number of cycles) from the
[FSK/Trig/Sync/Extmod] connector at the start of the burst.
⚫ Manual trigger: The generator outputs a pulse from the [FSK/Trig/Sync/Extmod]
connector at the start of the burst.
⚫ External Trigger: The [FSK/Trig/Sync/Extmod] connector is used as the input
terminal of external trigger signal and has no trigger output.
